earn To all whom it may concern:

Be itknown that 1, JAMES H. PIOKETT, a

Queen, in the county of Eddy and State of New Mexico, have invented new and useful Improvements in Gates, of which the following is a specification.

This invention relates to gates, particularly to that type which does not require manual manipulation for the opening and closing thereof, and has for its object the provision of a gate embodying a pair of similar pivoted sections which are connected with levers engaged by operating treadles whereby the gate sections will be automatically swung to open position by engagement of a vehicle upon the treadles at either side of the gate, the sections returning by gravity to. their closed positions when the vehicle passes from the treadles at the opposite side of the gate.

An important object is the provision of a gate of this character in which the supporting posts are disposed at an angle to the road bed and diverge upwardly and in which each longitudinal bar of the section is individually pivotally connected with the supporting posts whereby compact folding of the bars constituting the gate sections will be accomplished when the sections are swung to open position. v v

A further ob'ect is the provision of a gate of this character in which the operating.

treadles are adjustably connected with the actuating levers whereby the gate may be opened by engagement of heavy or light vehicles upon the treadles.

A further object is the provision of a gate of this character which will be comparatively simple and inexpensive in manufacture, easily' installed for use, eflicient in operation, durable in service, and a general improvement of the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawing, in which Figure 1 is afront elevation of the gate in its closed position,

Fig. 2 is a top plan view thereof,

Fig. 3 is a sectional view on the line 3-3 of Fig. 2, showing the gate in its open position, 1

Specification of Letters Patent.

of citizen of the United States, residing at Patented Aug. 17, 1920.

Application filed September 15, 1919. Serial No. 323,813.

Fig. 4c is a sectional view on the line 44:

Fig. 2,

Fig. 5 is a sectional view of the gate showing means for adjusting the position of the treadles for varying the leverage, .and

Figs. 6 and 7 are detail views of the adjustable elements.

Referring more particularly to the drawing, the numeral 10 designates the supporting frame of the gate which includes a plurality of boards or planks rigidly secured together. Secured within the frame 10 and extending transversely thereof at its central portion are spaced transverse bars 11.

p The numeral 12 designates the supporting posts of thegate, each of which is formed of two similar bars 13 secured upon the outer sides of the transverse bars 11 and connected at their upper ends by blocks 14:. The posts 12 are inclined in respect to the bars 11 and diverge upwardly in respect to each other. The line wires of the fence are secured to the members 13 of the post in the usual manner.

The gate proper is formed of two similar sections 15, each of which comprises bars 16, 17 and 18 which are of varying lengths, as shown, and which are pivotally connected at 19 between the members 13 constituting the posts. The inner ends of these gate bars are pivotally connected with diagonally extending strips 20 whereby they will be held in properly spaced relation. The inner ends of the gate bars are cut square and are adapted to abuttingly engage each other when the gate sections are in their closed positions. of the upper gate bars 16 extend beyond the The outer ends posts 12 and have pivotally connected therewith links 21, or suital'ile flexible members which extend downwardly and which are 'pivotally connected with the ends of substantially'horizontal levers 22 which extend in lapped relation to each other and which are pivotally mounted at 23 between the transverse bars 11 of the frame. The upper edges 'of the levers 22 are curved upwardly, as

shown, to provide abutment :portions 24. which extend above the upper edges of the transverse bars 11 for a purpose to be described.

In order that the gate sections may be automatically opened upon the approach of a vehicle, I provide treadle members 26 and 27 which are disposed upon opposite sides of the gate and which. have their outer ends pivotally connected with the frame 10, as shown at 28. The inner ends of these treadle members are connected for simultaneous movement by means of flexible members 29. lVhen the parts of the gate are.

assembled, the inner ends of the treadle members 26 and 27 are disposed upon the abut ment portions 24 of the levers 22, as clearly shown.

The operationof the gate is as follows: The gate sections 15 being in their lowered or closed position, as clearly shown in Fig. '1, when a vehicle is driven upon the treadles 26 or 27, pressure will be brought to bear upon the abutment portions 24 of the levers which will result in the levers moving downwardly upon their pivot points 23 into the position shown in Fig. '3, whereupon the treadles will engage upon the top edges of the transverse bars 11 of the frame. This comparatively slight depression of the inter: mediate portions of the levers will result in a much greater degree of movement at the ends of the levers to which the links 21 are connected. Downward movement of, these ends of the levers will pull the links21 downwardly'and will consequently exert a pull upon the projecting outer ends of the gate bars 16.v Downward movement of the outer ends of the gate bars 16 will result in the gate sections being swung upwardly upon the pivots 19 into the position shown in Fig. 3. The bars 16, 17 and 18 of the gate sections will then be disposed in a substantially vertical position with the-bars engaging against one another and occupying but little space The gate sections are limited in their upward movement by engagement of the edges of the bars 16 with one another. The gate sections will remain in their elevated positions as long as the vehicle remains upon any portion of the treadles 26 and 27. As soon as the vehicle is driven,

off the treadles, the weight of the gate sections will return the gate sections to their closed positions. The weight of the outer ends of the levers will return the treadles to their initial positions. It will be seen that depression of a right handle treadle will elevate the left gate section and depression of a left hand treadle will elevate the right gate section.

Though I have shown the pivotal connections of the bars 16, 17 and 18 with the members 13 as merely rods, it will of course be readily understood that I may employ any suitable type of hinge at these points as ractice may prove advisable.

11 order to provide for adjustment of leverage, I have shown in Fig. 5 and the succeeding figures, means for shifting the points of connection of the treadles with the actuating levers. More specifically, the

treadles 26 and 27 have provided upon their undersides, yokes 30 which may beengaged tions 24 of the levers The-sockets 81 are ordinarily covered by steel straps or strips 82 which pass through the yokes 30. By engaging the yokes within the sockets farthest from the pivot points of the levers, the gate may be opened by lighter-weight vehicles than when the yokes' are engaged within the sockets nearest the pivot points.

In this form it understood of course that the connection of the treadles with the frame must be also laterally adjustable.

' From the foregoing description and a study of the drawing it will be apparent that I have thus provided a comparatively simply constructed and very easily operated gate which will automatically open when-a vehicle is driven onto the approach treadles, which will remain in open position until the vehicle passes entirely over the treadles, and which will automatically close by gravity as soon as the vehicle has left the approach treadles. It will also be noted that when the gate sections are swung to their open positions the bars constituting the gate sections will swing into contact with one another and will consequently be folded compactly to occupy but. little space so as to extend a minimum distance from the inner facesof the gate posts.

While I have shown and described the preferred embodiment of the invention, it will of course be readily understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention nor the scope of the subjoined claims.

Having thus described my invention, I claim V 1. A gate of the character described comprising a supporting frame disposed within a roadway, a pair of upwardly diverging posts secured to said frame at the intermediateportion thereof, a pair of'similar gate sections adapted to bridge. thespace between said posts and each including a plurality of normally horizontally disposed bars individually pivotally connected with said posts and diagonally extending strips connectingsaid bars, one bar of each gate sec tion projecting outwardly beyond the associated post, a pairv of transversely disposed levers pivotally mounted in said frame and disposed in overlapping relation with their posed upon oppositesides of the gate sections and bearing upon the intermediate portions of said levers.

2. A gate of the character described comprising a supporting frame disposed in a roadway, a pair of upwardly diverging actuate the gate sections, and means for posts secured to said frame at the intermediate portion thereof, a pair of similar gate sections adapted to bridge the space between said posts and pivotally mounted upon said posts for swinging movement in a vertical plane, one bar of each gate projecting beyond the associated post, a pair of transversely disposed levers pivoted at the intermediate portion of the frame and connected with the projecting bars of the gate sections, treadle members pivoted in the frame and engaging said leverswhe'reby to varying the points of connection of said treadles with said levers comprising yokes secured upon the undersides of said treadles, said levers being provided each with a plurality of sockets within a selected one of which the associated yoke may be enaged, and strips secured upon the top edges of the levers and passing through the yokes.

In testimony whereof I my signature.

JAMES H. PIOAKETT.
